The medium handling apparatus includes a deposit/withdrawal unit configured to separate each individual medium and accumulate the medium, a discrimination unit configured to discriminate whether the media are abnormal and types of the media, a medium storage unit including a plurality of recycling cassettes, a temporary storage unit configured to temporarily store media discriminated as normal media, and a conveyance path configured to convey the media. Media in each of the recycling cassettes are temporarily stored in the temporary storage unit to confirm the number of media remaining in the recycling cassette, and the media in the temporary storage unit are conveyed back to and stored in the recycling cassette when the number of remaining media is sensed.

TECHNICAL FIELD

The present invention relates to a medium handling apparatus and method, and more particularly, to a medium handling apparatus and method for tallying media such as banknotes, checks, etc. therein.

BACKGROUND ART

In general, an automated teller machine (ATM) includes a medium handling apparatus for processing a deposit or a withdrawal of medium such as a banknote, a check, and the like.

The medium handling apparatus includes a deposit/withdrawal unit having a medium dispenser and a medium receiver which include a plurality of rollers so that a customer may insert or take out media for a deposit or a withdrawal, a discrimination unit for discriminating whether the media deposited or withdrawn through the deposit/withdrawal unit are abnormal, a temporary storage unit for temporarily storing media distinguished by the discrimination unit to be normal media among media deposited through the deposit/withdrawal unit, a medium storage unit composed of a plurality of cassettes to store deposited media and dispense media contained therein, and a conveyance path for connecting the deposit/withdrawal unit, the discrimination unit, the temporary storage unit, and the medium storage unit to each other and conveying media.

A display part provided on a rear side of the ATM displays the number of media stored in the medium storage unit of related medium handling apparatus. The display part may display the number of remaining media in each medium storage unit.

In this case, the number of remaining media displayed in the display part may differ from the number of media that actually remain in the medium storage unit. For example, when two media are separated in a medium storage unit and pass through the discrimination unit, the discrimination unit may not recognize the two media. Then, the number of media that actually remain in the medium storage unit does not coincide with the number of remaining media displayed in the display part.

Therefore, a teller should perform a tallying task to examine whether the number of remaining media displayed in the display part coincides with the number of media that actually remain in the medium storage unit. Such a tallying task involves separating each individual medium stored in the medium storage unit, determining the number of media by passing the separated media through the discrimination unit, and then storing the media in another medium storage unit. To perform the tallying task, the other medium storage unit should be empty.

In general, an ATM includes a supplementary/retrieval cassette to refill or retrieve media, and it is possible to perform the tallying task of determining the number of media remaining in a medium storage unit by using an empty supplementary/retrieval cassette.

However, in the case of an ATM which includes no supplementary/retrieval cassette, a teller must install an empty cassette in the ATM and then perform the tallying task. Therefore, the tallying task is inconvenient and time consuming.

Korean Patent Publication No. 10-2013-0075483 “Apparatus for Bill Receiving and Dispensing and the Method Thereof” discloses technology in which a supplementary/retrieval storage is used to perform the aforementioned tallying task. However, in the case of an apparatus having no supplementary/retrieval storage, it is difficult to perform the tallying task.

Medium conveyance paths in a handling apparatus according to an exemplary embodiment of the present invention will be described below with reference to FIGS. 2 to 7.

Deposited media counting and rejection processes will be described with reference to FIG. 2.

When a user inserts media into the internal space 111 of the deposit/withdrawal unit 110 for a deposit, the media are each individually separated by the separator 112 and then conveyed to the discrimination unit 120 through the first conveyance path 310.

Normal media discriminated by the discrimination unit 120 as normal are passed through the second conveyance path 320 (321, 322, and 323) and temporarily stored in the temporary storage unit 130 by the separator/accumulator 131 such that a deposited medium counting process is finished.

When a medium is discriminated as a reject medium by the discrimination unit 120, the direction of the three-way switch gate 390 is set so that the second upper conveyance path 322 and the third conveyance path 330 are connected. The reject medium discriminated by the discrimination unit 120 is passed through the second lower conveyance path 321, the second upper conveyance path 322, and the third conveyance path 330, is accumulated in the internal space 111 of the deposit/withdrawal unit 110 by the accumulator 113, and then is taken out by the user, such that a deposited medium rejection process is finished.

After the deposited medium counting process is performed as described above, a deposit reception process proceeds when the user inputs a deposit confirmation signal, and a deposit cancellation process proceeds when the user inputs a deposit cancellation signal.

When the deposit cancellation signal is input, the direction of the three-way switch gate 390 is set so that the second upper connective conveyance path 323 and the third conveyance path 330 are connected. The media temporarily stored in the temporary storage unit 130 are each individually separated by the separator/accumulator 131, passed through the second upper connective conveyance path 323 and the third conveyance path 330, accumulated in the internal space 111 of the deposit/withdrawal unit 110, and then taken out by the user, such that a deposit process is finished.

A deposit reception process will be described with reference to FIG. 3.

When the deposit reception process proceeds, the direction of the three-way switch gate 390 is set so that the second upper connective conveyance path 323 and the second upper conveyance path 322 are connected. The media temporarily stored in the temporary storage unit 130 are each individually separated by the separator/accumulator 131, passed through the second upper connective conveyance path 323, the second upper conveyance path 322, the second lower conveyance path 321, the discrimination unit 120, the first connective conveyance path 350, and the fourth conveyance path 340, and accumulated in a recycling cassette 210, such that a deposit process is finished. When a plurality of types of media are deposited, the media may be stored in a plurality of recycling cassettes according to type of media.

A withdrawal and rejection process will be described with reference to FIG. 4.

When a user makes a withdrawal request, the direction of the three-way switch gate 390 is set so that the second upper conveyance path 322 and the third conveyance path 330 are connected. Media stored in a recycling cassette 210 are each individually separated by a separator/accumulator 211.

Each individually separated medium is passed through the fourth conveyance path 340 and the first connective conveyance path 350, and the discrimination unit 120 discriminates whether the media are abnormal. Media discriminated to be normal media by the discrimination unit 120 are passed through the second lower conveyance path 321, the second upper conveyance path 322, and the third conveyance path 330 and accumulated in the internal space 111 by the accumulator 113 of the deposit/withdrawal unit 110. The media accumulated in the internal space 111 are taken out by the user such that a withdrawal process is finished.

A medium discriminated as a reject medium by the discrimination unit 120 is directly conveyed to the reject cassette 220 through the second lower conveyance path 321 and the second connective conveyance path 360 as indicated by the path of the broken line in FIG. 4.

As described above, the second connective conveyance path 360 diverged from the second conveyance path 320 is provided in the rear portion of the ATM, and the reject cassette 220 is disposed behind the recycling cassettes 210. Therefore, when a medium to be withdrawn is rejected, the reject medium may be discriminated by the discrimination unit 120 and then directly stored in the reject cassette 220 without being temporarily stored. Consequently, it is possible to reduce a handling time of the reject medium and shorten a conveyance path of the reject medium.

Retrieval of lost media will be described with reference to FIG. 5.

When a user forgets to take out media accumulated in the internal space 111 of the deposit/withdrawal unit 110 in a withdrawal process, the media become lost medium. In this case, the media are each individually separated by the separator 112, passed through the first conveyance path 310, the discrimination unit 120, the second lower conveyance path 321, and the second connective conveyance path 360, and stored in the reject cassette 220.

An internal tallying process will be described with reference to FIGS. 6 and 7.

First, a user inputs a signal for tallying the number of media stored in the recycling cassettes 210.

When the tallying signal is input, media are each individually separated by a separator/accumulator 211 in any one of the plurality of recycling cassettes 210, passed through the fourth conveyance path 340, and conveyed to the discrimination unit 120 as shown in FIG. 6, and the media are discriminated by the discrimination unit 120.

Media passed through the discrimination unit 120 are passed through the second lower conveyance path 321, the second upper conveyance path 322, and the second upper connective conveyance path 323, and stored in the temporary storage unit 130.

When all the media of the recycling cassette 210, which is a tallying target, are stored in the temporary storage unit 130 through such a process, the media of the temporary storage unit 130 are separated again and passed through the second upper connective conveyance path 323, the second upper conveyance path 322, the second lower conveyance path 321, the discrimination unit 120, and the fourth conveyance path 340, and stored in the recycling cassette 210, which is the tallying target, as shown in FIG. 7.

In this case, the number of media may be sensed by the discrimination unit 120, or a sensor provided in the conveyance path 320 or 340 may sense whether media are passed through.

When the number of media of the recycling cassette 210, which is the tallying target, is determined through the above process, the number may be displayed on a display (not shown) so that the user may see the number.

When tallying of the recycling cassette 210 is completed as described above, tallying of the other recycling cassettes 210 is performed through the same process.

Next, a process of refilling a recycling cassette 210 with media due to a deficient number of media will be described.

In a method of refilling media, the deposit/withdrawal unit 110 or the temporary storage unit 130 may be used.

First, when a user wants to refill a recycling cassette 210 with media by using the deposit/withdrawal unit 110, the user inserts media into the deposit/withdrawal unit 110. The inserted media are separated one by one, passed through the first conveyance path 310, and discriminated by the discrimination unit 120. After being discriminated, normal media are stored in the temporary storage unit 130, and the media stored in the temporary storage unit 130 are stored in the recycling cassette 210, such that the recycling cassette 210 is refilled with the media. In this case, a conveyance path of the media is the same as that shown in FIGS. 2 and 3.

Next, when a user wants to refill a recycling cassette 210 with media by using the temporary storage unit 130, the user opens the door 135 provided in the temporary storage unit 130 and inserts media for refilling the internal space 134.

The media in the internal space 134 are separated, passed through the second upper connective conveyance path 323, the second upper conveyance path 322, and the second lower conveyance path 321, and conveyed to the discrimination unit 120 such that the media are discriminated. Media discriminated as normal media are passed through the first connective conveyance path 350 and the fourth conveyance path 340 and stored in the recycling cassette 210 to be refilled. In this case, a conveyance path of the media is the same as that shown in FIG. 3. A medium discriminated as reject medium by the discrimination unit 120 is passed through the first connective conveyance path 350 and the fourth conveyance path 340 and stored in the reject cassette 220.

As described above, according to exemplary embodiments of the present invention, by using a temporary storage unit, it is possible to perform a tallying task even when there is no empty cassette in an ATM, such that the internal space of the ATM can be efficiently used.
